Pomegranate bioactive constituents target multiple oncogenic and oncosuppressive signaling for cancer prevention and intervention.

Cancer remains to be the second highest cause of mortality in our society, falling just short of heart disease. Despite major advancement in cancer therapy over the past decade, momentum has been gaining for an alternative approach of using naturally-occurring and dietary agents for cancer prevention and management. Research on pomegranate (Punica granatum L.), a fruit of the Punicaceae family, has shown enormous potential for cancer prevention and intervention. In addition to a rich source of polyphenols, including flavonoids and ellagitannins, in its juice, pomegranate also houses hundreds of other phytochemicals in its pericarp, seed, flower, bark, flowers and leaves. These phytochemicals provide powerful antiproliferative, anti-inflammatory, antioxidant, anti-invasive, antimigratory, anti-angiogenic and anti-metastatic effects without significant toxicity. This makes the use of its various extracts a very attractive strategy to our current battle against cancer. This review article presents a systematic, comprehensive and critical review of research on pomegranate-derived products in both cancer prevention and intervention. It discusses the chemical constituents of pomegranate, the results of both preclinical (in vitro, ex vivo and in vivo) and clinical studies on the anticancer effect of pomegranate phytochemicals and molecular targets in numerous types of cancers, such as breast, gastrointestinal tract (oral, colon, liver and pancreas), gynecological (uterine and ovarian), hematological (lymphoma, leukemia and myeloma), lung, neurological (glioma), urogenital (bladder and prostate), bioavailability, pharmacokinetics and safety of pomegranate constituents. In order to guide the direction of future research, we have also included current limitations and challenges in the field and our post analysis recommendation.

Adrenocorticotropic hormone gel in the treatment of systemic lupus erythematosus: A retrospective study of patients.

OBJECTIVES: Acthar Gel is a long-acting formulation of adrenocorticotropic hormone (ACTH) with anti-inflammatory effects thought to be mediated in part through melanocortin receptor activation. This study was initiated to understand the role of Acthar Gel in SLE treatment in rheumatology practices. METHODS: This is a retrospective case series of nine adult female patients treated with Acthar Gel for at least six months at five academic centers. Treating physicians completed a one-page questionnaire on lupus medications, disease activity, and outcomes. Clinical response was defined using SLEDAI 2K and improvement in the clinical manifestation(s) being treated. RESULTS: The most common clinical SLE manifestations/indications requiring therapy with Acthar Gel were arthritis, rash, and inability to taper corticosteroids. The mean SLEDAI 2K score at baseline was 5.8 ± 5.0 (range 0-16). Six patients were concomitantly treated with corticosteroids (mean dose 18.3mg/day). All patients were on background SLE medications including immunosuppressives. Seven of nine patients had an overall improvement, with a decrease in SLEDAI 2K from 5.8 ± 5.0 at baseline to 3.5 ± 2.7 (range 0-8); four of five patients had improvement or resolution in arthritis, and one of two patients had resolution of inflammatory rash. Four patients discontinued corticosteroids and one patient tapered below 50% of the initial dose by 3 months of treatment with Acthar Gel. No adverse events were reported. CONCLUSIONS: This study suggests a role for Acthar Gel as an alternative to corticosteroids in the treatment of SLE. Acthar Gel appears to be safe and well-tolerated after 6 months of treatment, with a significant reduction in disease activity.
